Abstract

Medium Sterilization which has been packaged in the baglog on the oyster mushroom cultivation, one of them can be done with a steam technique using the drum. Commonly used fuel is firewood that could be assisted by using coal or kerosene or LPG gas. Rice husk as alternative fuel of kerosene and firewood can be used as fuel for the medium sterilization. The husk which used in the sterilization process of oyster mushrooms medium for 6 hours, 8 hours, and 10 hours as much as 55.5 kg, 60 kg and 67 kg. The efficiency which obtained in the medium sterilization of oyster mushrooms with using rice husk is reached 45.23% in the medium sterilization for 8 hours.   Keywords: Medium, oyster mushrooms, rice husk, sterilization

Abstract

Sterilization media were done in drum. Fuels LPG.is used for the fuel Efficiencies of the fuel gained in the media sterilization oyster mushrooms for 6 hours is 40.74%, meanwhile efficiencies of the fuel for 8 and 10 hours is 59.57% and 53.14%. The physical and economical research of the white oyster mushrooms sterilization process for 8 hours produces the highest efficiency.   Keywords: Medium, oyster mushrooms, LPG, sterilization

Abstract

Husk furnace is used for cooking fuel chaff with the aid of air flow in the furnace. One measurement of the husk furnace efficiency can be studied by varying the size of the primary air holes on the body of the furnace. In this study, a hole measuring 22 cm X 24 cm obtained by the rate of fuel consumption of 6.03 kg / hour of heat energy needed to boil water as much as 6 liters is 2575.00 kcal / h and 14.32% efficiency furnace. While in the hole measuring 22 cm X 8 cm and 22 cm X 16 cm, respectively 12.92% and 12.87% efficiency furnace, not significantly different.   Keywords: chaff, husk furnace, ukuruan primary air hole, furnace efficiency
